New to the board and just have a few questions. I just got my motors set up and the are moving at a lightning speed of about 1 inch per min but at least they are moving. I am retrofitting a Practical cnc plasma 4x4 table.
I bought a kit from Tom at CandCNC I have 740 oz steppers on the x and y and 850 oz servo on the z axis with gecko drives. I have asked Tom a million questions already with the set up and thought it would be best to move on to the forum.
X and Y axis---The belt reduction from the motor to the pinion drive is 1-2.5 and the distance of travel on the rack is 2.625 inches per rotation of the pinion gear assuming 200 steps per revolution and 10x micro stepping on the gecko my steps per inch should be 1905 Right?
?
Z axis it takes 5 rotations of the z axis to move 1 inch 5:1 assuming 500 encoder steps per revolution my step set up would be 2500 right?
?
I would like my table to move at at least 200 inches per min so this figure would go in the velocity box? what would be a reasonable number for the acceleration box? and the step pulse and Dir Pulse numbers have me completely bamboozled
Please help me
